Always looking for new ideas and tech to test on PCP guns I seen this regulator on EBay.
https://www.ebay.com/itm/0-2200psi-Output-Regulator-Valve-Adjustable-Paintball-0-825-14NGO-Threaded-/173873529029 (https://www.ebay.com/itm/0-2200psi-Output-Regulator-Valve-Adjustable-Paintball-0-825-14NGO-Threaded-/173873529029)
I ordered 2 to test out but after looking at the construction I determined that they were unsafe at ANY pressure. There are only 3 threads of engagement on both ends and both are machined terrible to the point I believe you will absolutely have a failure. The threads on both ends are very thin and have razor sharp peaks also the internal thread is .040 out of tolerance to boot!! Let’s not even talk about the anodizing I’ll let the pics do that. Do Not Use This Regulator and please share this on other forums or chat rooms.

Thanks Travis! It's folks like you that save the rest of us from a lot of heartache and pain! :o Literally! :P
Looking forward to receiving my Raptor Mini with a safe adjustable regulator! ;D

Sometimes I swear they are trying to kill us... >:(

No problem. Its a shame because its a great idea just poorly executed.

Could be LOL. Bad part is I really want to test it out but cant :(

Looking at the various vendors who sell this I can see there has been many sold(2 to me) So If you have one or know someone who has one take it off and send it back please. IT will fail for sure ,maybe not immediately but then again probably.
-
I’m not even sure how that works! Comparing it to the one on the JSAR website, looks as though that one’s missing the foster fitting! Not that it matters, I won’t be getting one, but it appears they forgot more than just a half dozed more threads!!! :o

Travis, you got it all wrong, you're supposed to use your garden hose to fill your tank. See pic hahaha :D :D :D :D :D :D :D :D

Oh yeah for them "charged " water bottles yup yup ;)
-
0-150 psi output? Maybe this is supposed to be used on a water pistol! :P
-
Have you pulled the guts out of it yet?
Seems to me there was a similar product on another forum a year or two back which it turned out to be a flow regulator (ie...needle valve)...not a pressure regulator at all.

Yes it’s a pressure regulator from 150 to 2200 psi. It’s like a ninja regulator turned sideways

HPA = no
LP Water Pistol = yes
Imagine a "squirt gun" using a big regulated CF bottle at 150 PSI. Bet squirrels would know they got "wet".
Travis, thanks for sharing.
-
i think those are good for 50psi. you still get projectile effect when they fail.
i did test these regulators from 3000psi input. to 2000psi output. but it creeps like a loose rectum to 2500psi. did test it behind ar500 steel though. havent failed yet but dont wanna try again
-
Travis, just curious.... You say it's like a Ninja regulator turned sideways.... I assume that means that the adjusting knob moves either the seat or compresses the Belleville stack?.... If would further assume that the Piston and Bellevilles must be inserted into the body under that knob?.... That being the case, what happens if you undo the adjuster all the way?.... Is there anything to prevent it from flying off the side of the regulator?....

This should explain things . There is no means to keep knob from being unscrewed under pressure all the way.

Well, that explains where the foster fitting is, not that he could get it screwed into the regulator! Interesting that you can back the adjuster completely out of the regulator. I guess that would net you the 0 psi! Scary! :o
-
Actually, the adjusting knob has conventional RH threads (lefty loosey)…. and if you watch the video, unscrewing it increases the pressure.... At some point, the travel of the Bellevilles should become the limiting factor to the maximum adjustment pressure.... Unless I am mistaken, unscrewing it further, once the Bellevilles are compressed flat by the air pressure (2200 psi?)…. or no longer have preload on them (depending on their location, I suspect they put preload on the end of the piston) would not increase the pressure further.... I am somewhat alarmed that the knob might be unscrewed while under pressure to the point of it being launched by the HPA inside the regulator.... That, by itself, is an unsafe design, IMO.... Perhaps the piston might come out of the larger bore (which must be inside the adjusting knob), which would cause venting past the large O-ring…. presumably through the threads or a vent hole?....
Certainly there seems to be some safety questions beyond the thread quality, from what I can see....

Your correct at some point the poppet will have no effect and expose the pressure in the bottle to full output and additional turning will result in a big brass slug being launched at what ever its pointed at.
-
As long as the regulator seat does not leak, I would think the output pressure should stay at 2200 psi.... as long as the larger cylinder (ie the adjustment knob) stays sealed to the piston.... However, that still leaves that 2200 psi pushing outwards against the adjustment knob.... and if the threads disengage before the large O-ring comes out of the large cylinder, and the pressure vents somewhere.... the knob may indeed become a projectile, accelerated by that 2200 psi.... Without seeing the piston and bellevilles out of the knob.... and knowing if venting could occur.... there is no way to say for sure, of course....

Actually the piston is attached to the knob so you can turn it out and off the seat to expose full tank pressure to the adjuster. Just unsafe in many aspects.
-
the piston is attached to the knob
If that is the case, how can the piston move to regulate the airflow?.... I don't understand.... ???

look at the video when he pulls the knob out its all trapped inside the knob. Kind of hard to explain unless i do another video of the adjuster disassembly.
-
I looked at the video.... I would assume that inside the knob is a Belleville stack to provide the preload.... and then a piston, sealed with an O-ring.... with the large cylinder being machined inside the knob.... The piston must move inside the knob, no?....
You are correct, without seeing it disassembled I have no sure way of knowing how it works.... A simple photo or two of it disassembled would suffice.... Otherwise I should just shut up, as my comments are pure speculation….

JB WELD it to test, then toss it ?

If anyone is thinking about using one of these ebay regs, you should first look over some old "A Team" shows, where Mr "T" knocks off the valves of some oxygen bottles, to launch them as missiles through the wall. 3 cwappy threads on a 3000psi bottle, not me! 8) safety glasses! Ha!
